How did he go about learning sign language when he can't see?

As someone about to get a PhD in evolutionary biology, I can tell you're going to be fine. In fact, you're probably in better shape than most of your peers. I've taught plenty of undergrads - most coming from pretty conventional primary educations - and they are usually only interested in getting a decent grade. Ironically, your parents probably spurred you to have more curiosity about the world than most people, meaning you're likely to stay self-motivated. Self-motivation by itself will get you far during college and afterwards, but you're also gaining experience teaching yourself new things. If you come out of this with a good sense of how to learn things - which is basically the most important skill you can carry away from high school - you'll be unstoppable. Your areas of ignorance will fade quickly, and you'll have a much deeper understanding of your subjects than your peers when you enter college. If you're not already aware, Khan Academy, Coursera, and MIT opencouseware are all great free resources for teaching yourself these sorts of academic subjects. Just try to restrict yourself to one or two courses at a time - go for depth instead of breadth, and do the exercises.

Also, since you're trying to catch up in biology and thinking about doing CS, here's a full curriculum of free resources for bioinformatics (basically what I do): http://www.ploscompbiol.org/article/info%3Adoi%2F10.1371%2Fjournal.pcbi.1002632

Stay curious, aim high, and never stop challenging yourself. Good luck penis!
